<h4><a name = "tag_001_014_2543">&nbsp;</a>NAME</h4><blockquote>
unget - undo a previous get of an SCCS file (<b>DEVELOPMENT</b>)
</blockquote><h4><a name = "tag_001_014_2544">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

unget <b>[</b>-ns<b>][</b>-r <i>SID</i><b>]</b><i> file</i>...
</code>
</pre>
</blockquote><h4><a name = "tag_001_014_2545">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>unget</i>
utility reverses the effect of a
<i><a href="get.html">get</a></i>
<b>-e</b>
done prior to creating the intended new
delta.
</blockquote><h4><a name = "tag_001_014_2546">&nbsp;</a>OPTIONS</h4><blockquote>
The
<i>unget</i>
utility supports the <b>XBD</b> specification, <a href="../xbd/utilconv.html#usg"><b>Utility Syntax Guidelines</b>&nbsp;</a> .
The following options are supported:
<dl compact>

<dt><b>-r&nbsp;</b><i>SID</i>
<dd>Uniquely identify which delta is no longer intended.
(This would have been specified by
<i><a href="get.html">get</a></i>
as the new delta.)
The use of this option is necessary only if two or
more outstanding
<i><a href="get.html">get</a></i>
commands
for editing on the same SCCS
file were done by the same person
(login name).

<dt><b>-s</b>
<dd>Suppress the writing to standard output
of the intended delta's SID.

<dt><b>-n</b>
<dd>Retain the file that was obtained by
<i><a href="get.html">get</a></i>,
which would normally be removed from the current directory.

</dl>
</blockquote><h4><a name = "tag_001_014_2547">&nbsp;</a>OPERANDS</h4><blockquote>
The following operands are supported:
<dl compact>

<dt><i>file</i><dd>A pathname of an existing SCCS file or a directory.
If
<i>file</i>
is a directory,
<i>unget</i>
behaves as though each file in the directory were
specified as a named file,
except that non-SCCS files
(last component of the pathname does not begin with
s.)
and unreadable files are silently ignored.

If a single instance
<i>file</i>
is specified as -,
the standard input is read;
each line of the standard input is taken to be the name of an SCCS file
to be processed.
Non-SCCS files and unreadable files are silently ignored.

</dl>
</blockquote><h4><a name = "tag_001_014_2548">&nbsp;</a>STDIN</h4><blockquote>
The standard input is a text file used only when the
<i>file</i>
operand is specified as -.
Each line of the text file is interpreted as an SCCS pathname.
</blockquote><h4><a name = "tag_001_014_2549">&nbsp;</a>INPUT FILES</h4><blockquote>
Any SCCS files processed are files of an unspecified format.
</blockquote><h4><a name = "tag_001_014_2550">&nbsp;</a>ENVIRONMENT VARIABLES</h4><blockquote>
The following environment variables affect the execution of
<i>unget</i>:
<dl compact>

<dt><i>LANG</i><dd>Provide a default value for the internationalisation variables
that are unset or null.
If
<i>LANG</i>
is unset or null, the corresponding value from the
implementation-dependent default locale will be used.
If any of the internationalisation variables contains an invalid setting, the
utility will behave as if none of the variables had been defined.

<dt><i>LC_ALL</i><dd>
If set to a non-empty string value,
override the values of all the other internationalisation variables.

<dt><i>LC_CTYPE</i><dd>
Determine the
locale for the interpretation of sequences of bytes of text data as
characters (for example, single- as opposed to multi-byte characters
in arguments and input files).


<dt><i>LC_MESSAGES</i><dd>
Determine the locale that should be used to affect
the format and contents of diagnostic
messages written to standard error.

<dt><i>NLSPATH</i><dd>
Determine the location of message catalogues
for the processing of
<i>LC_MESSAGES .
</i>
</dl>
</blockquote><h4><a name = "tag_001_014_2551">&nbsp;</a>ASYNCHRONOUS EVENTS</h4><blockquote>
Default.
</blockquote><h4><a name = "tag_001_014_2552">&nbsp;</a>STDOUT</h4><blockquote>
The standard output consists of a line for each file, in the following format:
<p><code>
<tt>"%s\n"</tt>, &lt;<i>SID&nbsp;removed&nbsp;from&nbsp;file</i>&gt;
</code>
<p>
If there is more than one named file
or if a directory or standard input is named,
each pathname is written before each of the preceding lines:
<p><code>
<tt>"\n%s:\n"</tt>, &lt;<i>pathname</i>&gt;
</code>
</blockquote><h4><a name = "tag_001_014_2553">&nbsp;</a>STDERR</h4><blockquote>
Used only for diagnostic messages.
</blockquote><h4><a name = "tag_001_014_2554">&nbsp;</a>OUTPUT FILES</h4><blockquote>
Any SCCS files updated are files of an unspecified format.
During processing of a
<i>file</i>,
a locking
<i>z@file</i>,
as described in
<i><a href="get.html">get</a></i>,
and a
<i>q@file</i>
(a working copy of the
<i>p@file</i>),
may be created and deleted.
The
<i>p@file</i>
and
<i>g@file</i>,
as described in
<i><a href="get.html">get</a></i>,
are deleted.

None.
</blockquote><h4><a name = "tag_001_014_2556">&nbsp;</a>EXIT STATUS</h4><blockquote>
The following exit values are returned:
<dl compact>

<dt>0<dd>Successful completion.

<dt>&gt;0<dd>An error occurred.

</dl>
</blockquote><h4><a name = "tag_001_014_2557">&nbsp;</a>CONSEQUENCES OF ERRORS</h4><blockquote>
Default.
</blockquote><h4><a name = "tag_001_014_2558">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
None.
</blockquote><h4><a name = "tag_001_014_2559">&nbsp;</a>EXAMPLES</h4><blockquote>
